About the specified liquid level range1) During cooling operation with the liquid level lower than the specified range, the moisture of the atmosphere condenses on the exposed part of the cooling coil, causing the condensate to be mixed into the liquid.If the liquid level further decreases, it results in cooling capacity deterioration, and also causes a fault of the unit.2) During heating operation the liquid level lower than the specified range, the heating element of the heater is exposed or discolored, or may emit burning smell. If the liquid level further decreases, the heater activates the overheat protection device. This condition hinders normal operation, and also causes a fault of the unit.3) If the liquid level falls below the specified range due to liquid level fluctuations during operation, the liquid over-flows from the tank. To prevent the above 1) to 3) problems, be sure to maintain the liquid level within the specified range.Mount a float switch to ensure that the liquid level in the tank is within the specified range.2. Give thorough consideration to the layout of the partitions and inlet/outlet piping for the installation tank, so that the low-temperature liquid that has been cooled with the OILCON unit can be uniformly mixed with the high-tem-perature liquid returned from the machine.Installation place and oil pipingTo install this unit, select a place that meets the following conditions:Do not place an object that may block air flow within 500 mm from the air intake/exhaust port.1.

(The unit returns to the normal mode.)Check the remote signal, or examine the cause of the alarm. After taking a corrective action, execute auto-tuning again.3. Before starting auto-tuning, select an operation mode to determine the control target thermistor.

In Step 2, the machine may be over-cooled. To suppress machine over-cooling, specify an auto-tuning end condition in Parameter [n04].Parameter [n04]Outlet oil temperature decrease (Auto-tuning end condition)Setting range: 0.0 to 10.0C, Initial value: 8.0CWhen the tank liquid temperature has decreased by the temperature specified with this parameter, auto-tuning (data collection) ends.If the specified temperature range is too small, temperature control gain may not be correctly calculated. You should set this parameter to the maximum value in the range where it does not cause damage to the machine.5. To calculate more suitable temperature control gain based on the data collected in Step 3, you must specify a response coefficient in Parameter [n05]. (Through response coefficient adjustment, you can select whether to place importance on stability or response speed.)Parameter [n05]P and I gain calculation coefficient (Response coefficient)Setting range: 0.1 to 10.0, Initial value: 7.0Setting a smaller value improves stability. Setting a larger value improves response speed.If the set value is extremely large or small, the unit may not normally perform temperature control. First, you should execute auto-tuning with the initial value of 7.0.6. Depending on the condition of the control target (machine), the unit may not calculate suitable temperature control gain in a single auto-tuning operation. You should execute auto-tuning two or three times to average the calculated values, or use the value that most frequently appears (except for an extreme value).To calculate a more suitable temperature control gain, you may change Parameter [n05] (see [Note] 5. above).7.

Clean the air filter periodically to save power consumption.Maintenance/InspectionDaily maintenance/inspectionPeriodic maintenance/inspection Use thorough caution about operating liquid pollution control to maintain the pollution degree at NAS10 or lower level. Maintain the liquid level in the oil tank within the specified range. (See page.) Be sure not to allow liquid leak due to overflow. Never attempt to operate the unit without oil. Clean inside of the oil tank periodically to eliminate accumulated objects (cutting swarf etc.). Make sure that the power supply voltage is within the following range:50 Hz...........200 V 10%60 Hz...........200/220 V 10% Check if the compressor, fan or agitator does not abnormally sound during operation. Make sure that the Oil Cooling Unit does not abnormally shake during operation.To leave the unit unused for a long periodReturn filter (See page.) Clean the return filter at the tank return (liquid inlet) port periodically to prevent decrease in liquid level in the tank due to dust clogging.Air filter (See page.) Be sure to wash the air filter with water at 40C or lower temperature every two weeks.If the air filter is clogged with dust, the wind volume reduces, resulting in capacity deterioration. Also, the compressors protection device is activated, hindering smooth operation. Furthermore, it causes power consumption increase. Operating the unit without the air filter causes a fault. To remove the air filter, hold the bottom of the filter with both hands, and push it up while warping it forward.Condenser (See page.) If the condenser becomes extremely dirty, clean it with a brush, air blower, etc.(When cleaning the condenser fins, wear gloves. Otherwise, you may be injured by the sharp edges.)Exterior Wipe the exterior surface with a dry cloth. Never splash water over it. To clean the exterior, do not use a brush, polish powder, acid, solvent (benzine etc.) or hot water. Using such substances causes the paint to peel off.Cooling coil If cutting swarf or chips accumulate on the OILCON cooling coil surface, it results in cooling capacity deterioration, and also causes a fault of the unit. Check and clean the cooling coil periodically. Remove the OILCON unit from the tank, and clean the unit with a soft non-metal brush. During cleaning, be careful not to apply strong impact or force to the cooling coil. Mount a cover to the Oil Cooling Unit to prevent dust or water from entering inside of the unit. Be sure to turn OFF the main power supply. Be careful to keep oily dust off the condenser surface of the Oil Cooling Unit.156515lTH0013?^l\.m3b ..''=).'|j|;l37TroubleshootingMaintenanceTroubleshootingWhen the Oil Cooling Unit does not work well, first check the following points.If the problem persists, contact DAIKIN Contact Center with information on the following 1), 2) and 3) items.
